Former event planner Ronni Kahn saw this waste first hand and it changes something in her.

"At the end of an event, I'd had so much leftover food because I didn't want anyone to go home hungry. I wanted to be generous but we'd end up with mounds of food," Kahn told The Huffington Post Australia.

"One day I thought there was food being wasted, and there were people going hungry, why don't I join the two?"
